Halogenated supports and supported activators

ABSTRACT

The present invention is a halogenated support, supported activator and supported transition metal catalyst system involving reacting a carrier containing reactive functionalities with a halogenated organic in the presence of base and contacting a catalytic activator of the formula [C+] −1 [M1(Q 1 −Q n+1 )] and/or M n Q n  a transition metal catalytic precursor with the halogenated support.

BACKGROUND OF THE INVENTION

[0001] Transition metal catalysts, i.e., Ziegler-Natta and metallocenes, generally cannot be practically used for gas or slurry phase polymerization unless sufficiently supported. The use of supported catalysts offers the possibility of gas and slurry phase compatibility. Control of the particle size distribution of the polymeric product in the various polymerization processes eliminates or reduces the extent of reactor fouling.

[0002] Supported catalysts for olefin polymerization are well known in the art. These catalysts offer, among other things, the advantages of being useable in gas or slurry phase reactors, allowing the control of polymer particle size and thereby the control of the product bulk density. Gas phase reactors also eliminate the need for a solvent and the equipment for solvent handling during separation of the solvent from the resin. However, it is known that transition metal catalysts, particularly metallocene catalysts, are deactivated by supports that contain reactive functionalities, such as silicas which are oxide supports.

[0003] Accordingly, when using supported polyolefin catalysts, it is often desired to remove or reduce hydroxyl groups and other reactive functionalities from the support particles before and/or during manufacture of the supported catalyst. Removal of the reactive functionalities is often desirable since they will often react with the catalyst thereby deactivating it.

[0004] For example, in the past, various thermal and/or chemical treatments have been used in an effort to achieve dehydroxylation of the oxide particles.

[0005] Thermal treatments (i.e., calcining) are advantageous from the point that they do not add undesirable chemicals to the support and that they are relatively simple inexpensive processes. Unfortunately, thermal treatments are often ineffective for achieving a high degree of dehydroxylation. Further, for many porous oxide supports (e.g. silica gel), thermal treatments often result in an undesirable loss of pore volume, shrinkage of the pores and/or loss of surface area.

[0006] Furthermore, a variety of chemical treatments have been attempted to remove or deactivate reactive functionalities. Many types of chemicals have been used such as organo aluminum compounds, magnesium chloride/ dehydrating agent combinations, organosilanes, halosilanes, silanes, etc. These various chemical processes are often expensive and may result in the addition of undesired or complicating constituents to an oxide support.

[0007] Thus, there remains a need for improved catalytic supports and supported activators having the undesired reactive functionalities deactivated.

[0008] Moreover, it is sometimes desirable to impart different characteristics to the support surface. The attachment of selected organic moieties to the support effects the characteristics of the support and hence the catalytic nature of the catalyst and/or activator placed on the support.

[0009] Thus it is an object of this invention to provide a method to deactivate reactive functionalities on catalytic supports as well to provide for a new support for transition metal catalysts and a supported catalytic activator.

[0010] Furthermore, it is an object of the present invention to provide a supported activator and a supported transition metal catalyst and/or catalyst system (support, activator and catalytic precursor) capable of not only producing polymers, but also providing a catalyst with hydrogen sensitivity so as to allow use of hydrogen to control molecular weight in olefin polymerization reactors.

SUMMARY OF THE INVENTION

[0011] The invention provides supports, supported catalytic activators and supported catalytic systems, wherein the supports have unique surface chemical compositions. The present invention further includes methods for making and using such compositions.

[0012] In particular, the present invention uses halogenated organic moieties that are covalently bonded to the support surface. Reactive functionalities on typical catalyst supports, such as hydroxyl groups, known as catalyst poisons, are consumed and the halogenated, most preferably fluorinated, organics are bonded to the support in their stead. These halogenated organic supports are ideal for supporting transition metal catalysts, particularly metallocene and/or Ziegler-Natta catalysts, particularly when a borate and/or aluminate catalyst activator is used. The support and supported catalytic activator of the present invention imparts enhanced properties, including improved activity and reduced reactor fouling while obtaining a resin particle of good morphology, bulk density, and enhanced comononer incorporation.

[0013] In one aspect, the present invention is a support composition represented by the following formula.

Carrier—L—RX:,

[0014] wherein the Carrier is not particularly limited and includes any material capable of forming a covalent bond to the halogenated organic RX and includes inorganic carriers, inorganic oxide carriers and organic carriers. Of these, inorganic carriers and inorganic oxide carriers are particularly preferred.

[0015] RX is any halogenated organic, wherein X is a halogen group and typically is fluorine, chlorine, iodine, and bromine and mixtures thereof.

[0016] L represents the linkage resulting from the reaction of the support reactive functionality with a base (described below) that would be present on the support and capable of forming a covalent bond to the halogenated organic RX.

[0017] In another aspect of the invention, the invention provides a supported catalytic activator for use with transition metal catalytic precursor represented by the below formula.

Carrier—L—RX::[Compound A]

[0018] Where the Carrier, L, and RX are as described above and Compound A is a compound capable of forming an ionic complex when reacted with a transition metal catalytic precursor and is further represented by the formulas [C⁺]⁻[M^(n)(Q₁−Q_(n+1)) ] and M^(n)Q_(n).

[0020]⁻[M^(n)(Q₁−Q_(n+1)] is a compatible, large (bulky), non-coordinating anion capable of stabilizing the active transition metal catalytic species which is formed when the transition metal catalyst precursor is combined with the supported activator of present invention. These anionic coordination complexes comprise a plurality of lipophilic radicals covalently coordinated to and shielding a central charge-bearing metal or metalloid.

[0021] M^(n)(Q_(n)) is a large (bulky), non-coordinating, neutral species that is capable of stabilizing the active transition metal catalytic species which is formed when the transition metal catalyst precursor is combined with the supported activator of present invention. These anionic coordination complexes comprise a plurality of lipophilic radicals covalently coordinated to and shielding a central charge-bearing metal or metalloid.

[0022] In a third embodiment of the present invention, the support or the supported activator is combined (in any order of addition) with a transition metal catalytic precursor to provide a supported catalyst or a supported catalytic system. The support or the supported activator of the present invention may be combined with the transition metal catalytic precursor either prior to or during introduction to the polymerization reactor zone. Upon contact with the activator, the transition metal precursor reacts to form the active catalytic species.

[0023] The invention further includes the method for producing halogenated supports, supported catalytic activators, and catalyst systems as well, and methods for using the halogenated support in transition metal catalyst systems to polymerize olefins, diolefins, cyclic olefins and acetylenically unsaturated monomers to produce polymers, particularly polyethylene.

[0024] These and other aspects of the invention will be described in further detail below.

METHODS OF PRODUCING THE COMPOSITIONS OF THE PRESENT INVENTION

[0062] Making the Support

[0063] The methods of the invention generally encompass a step where reactive functionality containing carrier particles are reacted with a halogenated organic in the presence of a base whereby at least a portion of the reactive functionality groups are removed or eliminated and the halogenated organic groups are covalently bonded to the carrier particle surface.

[0064] The base reactant used is typically a metal hydroxide (such as NaOH or KOH), primary, secondary or tertiary amines (such as methylamine, dimethylamine, triethylamine, dimethylaniline and tributylamine), metal alkyls (wherein the metal is from Group 1, 2, 13, and 14 of the Periodic Table and the alkyl are C1-C8, including n-Butyllithium, dibutyl magnesium, trimethylaluminum, methyllithium). Preferred bases are NaOH, n-butyllithium, dibutyl magnesium, triethyl amine and tributyl amine. Most preferred bases are NaOH, n-butyllithium, and tributylamine and mixtures thereof.

[0065] When an aqueous basic solution is used, the resultant reaction product should have excess water removed.

[0066] The methods preferably involve formation of an initial mixture containing the carrier particles, a base and the halogenated organic. The initial mixture preferably also contains a solvent (preferably non-aqueous); however, neat mixtures of the carrier particles, halogen and base may be used. The ingredients forming the initial mixture may be combined in virtually any desired sequence to effect the desired transformation.

[0067] While the carrier particles may contain some free water, it is preferred that any free water be removed before the initial mixture is formed. For example, by solvent exchange, heating, and chemical reaction.

[0068] The carrier particles are preferably porous. The porosity of the particles is preferably dictated by the intended end use of the particles. Preferably, the porosity of the particles to be deactivated is such that the resulting particles would be suitable for use as polyolefin catalyst supports.

[0069] The initial mixture preferably contains a solvent to facilitate intimate mixing of the carrier particles and the reagents.

[0070] The solvent is preferably a non-aqueous solvent. Organic solvents such as C5-C10 hydrocarbons, typically, hexane, tetrahydrofuran, toluene, ether and heptane are generally preferred. The amount of solvent used is not critical, but amounts in excess of that needed to form a pourable slurry are generally unnecessary.

[0071] The mixing temperature depends on the solvent and base used and can vary from well below OUC to the reflux temperature of the solvent, preferably from about OUC to the reflux temperature of the solvent.

[0072] In general the method of the present invention comprises the steps of combining the carrier and the base and mixing a temperature in the range of from about −78° C. to the reflux temperature of the solvent (preferably from about 0° C. to the reflux temperature of the solvent). The mixing time depends on the mixing temperature. In general the higher the temperature the shorter the time required. Mixing should continue until the reaction between the carrier's functionality groups and the basic reagent is completed.

[0073] While reacting the support with the halogenated organic can generally be completed in a single reaction step, it is possible to repeat the reaction step by recovering the support particles and forming a new reaction mixture in the same manner as for the formation of the initial mixture.

[0074] Once the desired level of functionality has been accomplished, the support particles may be recovered from the mixture. The preferred level of the functionality is a approximately 10 mmoles per gram of support; more preferably, 0.1-5 mmole/g; and more preferably, 1-3 mmole/g. This can be determined by known analytical techniques, such as IR, NMR, and elemental analysis.

[0075] Preferably, recovery can be accomplished by simply evaporating the solvent and other reactants. In some instances, it may be desirable to wash the halogenated carrier with a solvent to further remove any residual reactants(such as the base), etc. Preferably, however, the reactants are selected such that they are all removable by volatilization. Preferably, the removal is conducted under at least a partial vacuum. If desired, techniques such as spray drying may be employed.

[0076] The carrier of the present invention will typically be in the form of a free flowing powder having the surface groups R as defined above used in the reacting step. The recovered product may be further treated as desired to place a catalyst or other constituents on its surface.

[0077] This support may be used to support a transition metal catalytic precursor or can be used in another embodiment of the present invention to prepare the supported activator.

[0078] Making the Supported Activator

[0079] The activator [C⁺]⁻[M^(n)(Q₁—Q_(n+1))] and/or M^(n)(Q_(n)) as defined above, is dissolved in the desired solvent described above, preferably toluene, C₅-C₁₀ hydrocarbons, and combined with the halogenated support to form a slurry. The reagents are mixed thoroughly using well known mixing and agitation techniques and can be mixed at any appropriate temperature depending on the reagents selected, preferably room temperature. This step can be performed after the halogenated support is prepared or can be accomplished simultaneously with the preparation of the halogenated support by combining all the ingredients in one step.

[0080] These materials can be combined at any temperature suitable for the reagents, typically from about −78° C. to the reflux temperature of the halogenated reagent, preferably from about OC to the reflux temperature of the solvent. This can be accomplished using multiple mixing steps. For example, the mixing can take place for one period of time at one temperature, e.g., −78° C. for two hours and then for another period of time at another temperature, e.g., reflux temperature for two hours. This stepwise (varying time and temperature) can be used for any number of mixing conditions. The time for mixing is dependent on the mixing temperature. In general, it is best to keep the temperature low so as to avoid decomposing temperature sensitive reagents. The protocol is selected so as to maximize the efficiency of the reaction.

[0081] Once the desired level of activator on the support is achieved the supported activator can be recovered by any of number of usual methods, typically by evaporating the solvent and other reactants.

[0082] Making the Supported Catalytic Systems

[0083] Transition metal (Ziegler Natta and/or metallocene) catalyst precursors can be placed on the support and/or supported activator of the present invention through various techniques. For example, once the halogenated support and/or supported activator is prepared, the catalytic precursor can be placed on the support through known techniques such as in a slurry, dry mixing or fluidized gas mixing well known to those skilled in the art. Moreover, an admixture of all necessary reagents can be prepared where the halogenated support, support activator and catalyst system are prepared simultaneously.

[0084] Furthermore, the supported activator and catalyst precursor need not be combined until introduced into the polymer reactor zone either before or during the introduction of the monomer feedstock.

METHODS OF USING THE COMPOSITIONS OF THE PRESENT INVENTION

[0085] Activation of the supported catalyst or catalytic system of the present invention may be accomplished by any suitable method for bringing the support and/or the supported activator into contact with the transition metal catalytic precursor to create the active catalytic species. Such mixing techniques include the mixing of the dry powders, mixing through gaseous impregnation or via a slurry composition in a solvent.

[0086] It is also possible to use any of the traditional transition metal catalytic activator co-catalysts which should be selected based on the catalytic system design and desired polymer characteristics.

[0087] The activated catalyst is useful to polymerize olefinic materials, particularly ethylene. Polmerizations of olefinic monomers can be accomplished by any number of well known techniques by having the olefinic material come into contact with the polymerization catalyst(s) in a reaction zone under appropriate conditions.

[0088] As used herein, “Polymerization” includes copolymerization and terpolymeriztion and the terms olefins and olefinic monomer includes olefins, alphaolefins, diolefins, strained cyclic, styrenic monomers, acetylenically unsaturated monomers, cyclic olefins alone or in combination with other unsaturated monomers. While the catalyst system of the present invention is active for this broad range of olefinic monomer feedstock, alpha-olefins polymerizations is preferred, especially the homopolymerization of ethylene or the copolymerization of ethylene with olefins having 3 to 10 carbon atoms.

[0089] “Polymerization techniques” for olefin polymerization according the present invention can be solution polymerization, slurry polymerization or gas phase polymerization techniques. Method and apparatus for effecting such polymerization reactions are well known and described in, for example, Encyclopedia of Polymer Science and Engineering published by John Wiley and Sons, 1987, Volume 7, pages 480-488 and 1988, Volume 12, pages 504-541. The catalyst according to the present invention can be used in similar amounts and under similar conditions to known olefin polymerization catalyst.

[0090] Typically, for the slurry process, the temperature is from approximately 0 degrees C to just below the temperature at which the polymer becomes swollen in the polymerization medium. For the gas phase process, the temperature is from approximately 0 degrees C to just below the melting point of the polymer. For the solution process, the temperature is typically the temperature from which the polymer is soluble in the reaction medium up to approximately 320 degrees C.

[0091] The pressure used can be selected from a relatively wide range of suitable pressures, e.g., from subatmospheric to about 350 Mpa. Suitably, the pressure is from atmospheric to about 6.9 Mpa, or 0.05-10 MPa, especially 0.14-5.5 Mpa. Pressure is dictated by the process and the desired product. In the slurry or particle form process, the process is suitably performed with a liquid inert diluent such as a saturated aliphatic hydrocarbon. Suitably the hydrocarbon is a C₄ to C₁₀ hydrocarbon, e.g., isobutane or an aromatic hydrocarbon liquid such as benzene, toluene or xylene. The polymer is recovered directly from the gas phase process or by filtration or evaporation from the slurry process or evaporation from the solution process.

[0092] The catalysts of the present invention are particularly suited for the gas phase or slurry process.

[0093] In addition to the examples of the present invention provided in the Examples 1-17, preferred supports, supported activators, and supported catalyst systems can be prepared from the following materials.
